In our course, we'll explore both BJT and MOSFET circuits. What do you know about the differences between these two?
I heard BJTs are current-controlled devices, while MOSFETs are voltage-controlled?
That's correct! BJTs require current at the base to allow current flow between the collector and emitter, while MOSFETs are controlled by voltage at the gate. Why do you think it's important to study both together?
To understand their applications in different systems and design effective circuits depending on the requirements?
Exactly! Learning to differentiate will give you a comprehensive view of their performances. It leads to informed decisions when designing circuits.
